About the SynthCard PCB

SynthCard is an open source PCB design by benjiaomodular, published on GitHub under the MIT license. It is a 2-layer board measuring 88.9 × 50.8 mm, with 16 components from 13 distinct parts.

Other key parts include the NE555P. By type, the board carries 4 capacitors, 4 resistors, 2 ICs, 1 connector and 1 diode.

It belongs with the audio and power & battery designs in this gallery.

Schematics under /KiCAD. Gerber files under /Fabrication. Panel design under /Inkscape.

This module produces a pulse/square wave at 9Vpp.

There are two knobs. Knob 1 controls the frequency. Knob 2 controls the pulse width.

The module can be powered using a 9V power supply. A battery should work too.
